SPEOIFICA'FION forming part Of Letters Patent N0. 604,798, dated May 31,1898. Application filed January15, 1898. Serial No- 666,771- (No model.)

To all whom it may concern.-

Be it known that we, JOHN WALTER SMITH and ALBERT H. ANTHONY, citizensof the United States, residing at WVorcester, in the county of Worcesterand State of Massachusetts, have invented a new and useful improvementin Governor Mechanism, of which the following, together with theaccompany- 111g drawings, is a specification sufficiently full, clear,and exact to enable persons skilled in the art to which this inventionappertains to make and use the same.

Our invention relates to the manner and means for connecting the leversof the revolving governor-balls with the endwise-reciprocatingvalve-operating spindle or rod for transmitting and converting themotion from the former to the latter in the operation of the governor,the objects of this invention being to provide an efficient anddesirable connection mechanism that will work easily and smoothlywithout looseness in the runn ngoints; also, to render the mechanismsimple and convenient for accurate manufacture, steady and durable inits working parts, not subject to rapid wear, and not liable toderangement when'i'n use. We attain these objects by the mechanismillustrated.

in the drawings, Figure 1 is a side view of a governor embracing ourinvention. Fig. 2 1s a transverse section at line am through theconnecting-joints. Fig. 3 is a vertical section through the valve-rodhead and joints. Fig. 4 1s a top plan of the joints and center block.Fig. 5 shows a separate view of one of the joint-rollers, and Fig; 6shows a modification in the position of the joint-rollers andfinger-pins.

In referring to parts, A indicates the rotary head or sleeve, providedwith pulley A and arms a and mounted to rotate on the tubular bearing13, that is fixed to the valveframe. (Not shown.)

(J (3 indicate the governor-balls, d the balllever pivots, E thesprings, A the spring-supporting bar, E the tension-regulatingscrew andplate, and F the valve-actuating rod, all of whlch parts may be ofsuitable or wellknown construction.

Our improved means for connecting the swinging ball-levers O with theendwise-movable valve-rod F comprises a swiveling piece or center blockmounted on the valve-rod head and running between oppositely-facedconical bearing-surfaces and having a hinging attachment with theball-levers composed of trahsversely-disposed j oint-rollers or rockingcylinders, in conjunction with finger-pins that engage holes in saidrollers perpendicular to their axis and have endwise or sliding movementtherein, while the rollers have rocking motion in their seats, thusaifording an easily operating, steady, and durable mechanism fortransmitting and converting the motion from the balls to the rod, as thelatter is thrown up and down by the action of the balls when they areefiected by various speeds of rotation. In this connection, G indicatesthe valve-rod head, which is formed with a cylindrical hub to which thevalve-rod F is attached by pin 3, also with a flange 4, have ing a conedtop surface and a center stud projecting above said flange. (See Fig.3.)

I indicates the center block, having a central opening with upper andunder conical bearing-seats to match the cone-flange 4 and to receivethe fiat cone-shaped cap or washer .l, that fits into the center blockand is secured to the center stud of the valve-rod head by a screw J,that is threaded into an axial opening therein. The center block I isthereby secured to revolve freely, but without backlash or tiltingmotion, on the head of the valve-rod.

M M indicate the joint-rollers, disposed at either side of the centertransverse to theaxis of the governor rotation and parallel with eachother, as'shown. Said joint-rollers are fitted to have easy rockingmotion in cylindrical openings in their support and are best arranged toextend from side to side of the center block, as illustrated. At thecenter the roller M has a hole m bored therethrough at a right angle tothe axis of the roller, (see Fig. 5,) and the joint-roll bearing isrecessed through its outer face, as at n, to permit entrance thereto. Iare each provided with a hard steel straight finger-pin P, that projectsrigidly therefrom and enters the hole m in the rollerM, fitting thereinclosely, but so as to slide easily inward and outward endwise.

The ends of the ball-levers When the ball-levers rise and fall, thefinger-pins and rollers accommodate themselves to the varying angularitybetween the levers and the center axis, maintaining a free workingconnect-ion withoutunnecessary loosenes's, the roller rocking, in itsseat to conform to the movement of the finger-pin and said finger-pinhaving a slight endwise movement in the hole 112 to accommodate thevarying distance between pivot centers as the levers swing up or down.This construction produces a very durable, efiicient, and desirablegovernor connection.

In Fig. 6 we have shown a modification in construction which may in someinstances be employed, if desired, and in which the position of thefinger-pins and rollers is reversed, the finger-pins P being fixed tothe center block I and the joint-rollers M seated in the ends of theball-levers C The operation in this instance is substantially the sameas that above described.

It will be understood that we do not make claim to the arrangement ofthe governorball,'the springs, and spring-ten'sion-adjusting devicesmounted on the rotating sleeve for operating a central valve-rod, assuch parts of the mechanism have heretofore been employed.

What we claimas of our invention, and desire to secure by LettersPatent, is-

1. In a governor, the combination with the ball-lever andvalve-actuating rod; of a center block running on the valve-rod head,and a connection .from said center block to said ball-lever consistingof the transversely-disposed j oint-roller and the finger-pin engagingwith said roller for operation substantially as set forth.

2. The combination, with the swinging governor-lever, and the swivelingcenter block carrying the endwise-movable rod; of thetransversely-disposed roller mounted to rock within a cylindrical recessformed in one of the parts, and a straight projecting fingerpin rigidlyfixed on the other part and extending into a hole formedin said rollerperpendicular to the axis thereof, and movable therein, substantially asset forth.

3. The combination, as described, of the valve-rod, the valve-rod headhaving the conical-faced flange and centering-stud thereon, theconical-faced washer fitting over said stud, its fasteningscrew, mountedto turn on said head and having cone-shaped recesses matching saidflange and washers, the governor-ball levers and a hinging jointconnection joining said center block and governor-ball levers,substantially as set forth. I

4. In combination, the rotatable sleeve having the bifurcated arms, thegovernor-ball levers pivoted to said arms, the central valverod havingthe conically-flanged head, the center block mounted on said head toturn freely between the conical bearing-surfaces, the joint-rollersarranged in transversely-disposed openings extending across the oppositeends of said center block, said rollers having a holethereinperpendicular to their axis, and the finger-pins respectivelyfixed in the governor-ball levers and fitting into the holes in thejoint-rollers, for the purposes set forth. Witness our hands this 12thday of January, 1898.
